It has been known for some time that, despite her character's death in the first film, Sigourney Weaver is planning to return to the world of Pandora for James Cameron's upcoming Avatar sequels. Today, she tells Vulture that not only will she appear in all three sequels (to be shot back-to-back), but teases that her character will "transform" in some way.
"It will be challenging for me," she tells the outlet. "I can't talk about it, but my part is a little different in each one. I'll transform somewhat."
Avatar 2 is scheduled for a December, 2016 release, Avatar 3 for December of 2017, and Avatar 4 for 2018. The original film remains the top grossing movie of all time with $2.782 billion at the worldwide box office.
